Used as a ligand in coordination chemistry, particularly in the formation of transition metal complexes for catalysis. Its structure allows for stable chelation with metals, making it valuable in homogeneous catalysts for organic transformations such as C–H activation and cross-coupling reactions. Also employed in the development of luminescent materials and metal-organic frameworks (MOFs) due to its ability to coordinate with metal ions that exhibit photophysical properties. Additionally, it serves as a building block in pharmaceuticals and agrochemicals where nitrogen-containing heterocycles enhance biological activity.
